Perhaps you should do movie. Comic costumes usually go through changes and they might change the comic costumes because of the new movie's popularity. It probably would be difficult to do, but maybe you can implement their comic costumes through a different color pallette. It is a great idea to add the guardians and new features! I am excited all over again! Here's an idea that you may or may not want to consider: You know about the new Mortal Kombat game where character's have different set of fighting styles (same character but different moves). Since you have all these fans asking their preferences for different move sets, you could make an option of having each character to have 3 different fighting styles. I understand you have limitations with the openbor engine but I just wanted to give you some ideas to brainstorm on. ( I like wolverine as he is, btw)
